The Principle of Steam Sterilization

Steam sterilization in an autoclave is performed under controlled conditions with the thermostatic trap. The process involves exposing items to direct steam at a specific pressure and temperature for a predetermined period. The most commonly used temperature setting for sterilization is 121 degrees Celsius (250 degrees Fahrenheit) at a pressure of 15 pounds per square inch, sustained for about 15 to 20 minutes, depending on the load and contents. This method is effective due to the moist heat carried by the steam, which efficiently kills microorganisms by denaturing enzymes and structural proteins.

Components of an Autoclave

Sterilization Chamber: The core component where items are placed for sterilization. It can vary in size from small tabletop units to large industrial autoclaves.

Steam Generator: Produces steam that is injected into the chamber. Some autoclaves are fitted with an in-built generator, while others might require an external steam source.

Control Systems: Modern autoclaves feature sophisticated electronic controls that allow precise manipulation of temperature, pressure, and timing. These systems often include safety features to prevent the operation under unsafe conditions.

Vacuum System: Used in pre-vacuum autoclaves to remove air from the chamber and ensure even steam penetration, especially crucial for sterilizing porous items or materials in packs.

Safety Valves and Locks: Ensure that the autoclave door cannot be opened while the chamber is pressurized, thus preventing accidents.

Types of Autoclaves

Gravity Displacement Autoclaves: The most common type, where steam is injected into the chamber, displacing the air, which is forced out through vents.

Pre-vacuum Autoclaves: These autoclaves initially pull a vacuum to remove all air from the chamber and then introduce steam. This type is more effective at penetrating complex items and deep packs.

Pass-through Autoclaves: Designed for laboratories and medical facilities to maintain a sterile barrier between different areas. Items can be loaded from one side and removed from another after sterilization.

Applications of Autoclaves

Medical Facilities: Used for sterilizing surgical instruments, hospital gowns, hospital operating room attire, and more.

Laboratories: Essential for sterilizing lab tools, especially in microbiology, where culture media and instruments must be kept sterile to avoid cross-contamination.

Industrial Applications: Used for curing composites and in the manufacturing of high-strength materials that require exposure to high pressure and temperature.

Operation of an Autoclave

The sterilization cycle involves several phases:

Loading: Items are loaded into the autoclave, ensuring that steam can circulate freely around each item.

Sterilization: The chamber is sealed, and steam is introduced at high pressure and temperature. The cycle's duration depends on the nature of the load and the set standards.

Venting and Drying: After sterilization, steam is vented, and if equipped, a drying cycle commences to remove any remaining moisture.

Best Practices for Using Autoclaves

Proper Loading: Do not overload the autoclave to ensure even steam distribution.

Regular Maintenance: Regularly check and maintain the autoclave to ensure it operates efficiently and safely.

Validation and Documentation: Keep detailed records of each cycle for quality and to satisfy regulatory requirements.
